[Distal lesions of the Fallopian tubes. Prognostic values of peroperative tubal biopsy].

78 biopsies were carried out during 63 distal tubal microsurgical operations, followed up for two years at least. The clinical outcome was studied according to the pathological state of the better tube: Viable pregnancies become more frequent with subnormal tubes (40%) and with tubes with moderate chronic salpingitis (65%). The risk of extra-uterine pregnancy is at a maximum with chronic cicatricial salpingitis (29.4%). Progressive chronic salpingitis results in only 6.6% viable pregnancies and will definitely constitute an indication for in vitro fertilization rather than microsurgery.
